摘要: 作者测定了聚三烯丙基氰尿酸酯(PTAC)树脂的孔结构及对Au(Ⅲ)的吸附性。包括pH值、初始金液浓度,共存金属离子存在下对金的吸附.实验结果表明,(PTAC)大孔吸附树脂对Au(Ⅲ)的吸附是通过分子链上氮或氧原子的孤电子对与H3+AuCl4-离子对形成弱键。

关键词: 大孔吸附树脂, 孔结构, 吸附性

Abstract: The pore structures and adsorption properties of these adsorbents were examined as a function of pH, initial gold concentration and selectivity. The experimental results suggest that the ion pair H3O+AuCl4- were adsorbed by the adsorbent through the formation of weak bond with the ester oxygen or nitrogen of the polymer matrix.
